The ACT Test Math Practice Test 55 Questions with Verified Answers Sine - CORRECT ANSWER Opposite/Hypotenuse Cosine - CORRECT ANSWER Adjacent/Hyptonuse Tangent - CORRECT ANSWER Opposite/Adjacent Circumference of a Circle - CORRECT ANSWER 2*Pi*R Area of a circle - CORRECT ANSWER Pi * R^2 Midpoint Formula - CORRECT ANSWER x1+x2/2 y1+y2/2 Linear Equation - CORRECT ANSWER Y=Mx+b M= - CORRECT ANSWER Slope B= - CORRECT ANSWER Y-intercept Pythagorean theorem - CORRECT ANSWER A^2 + B^2= C^2 How Many Degrees Are in a Triangle - CORRECT ANSWER 180 How Many Degrees are in a Circle - CORRECT ANSWER 360 Substitution Method - CORRECT ANSWER Elimination Method - CORRECT ANSWER In Mx+b When M is 0 - CORRECT ANSWER Y= M (Or it is 0) Sector of a Circle - CORRECT ANSWER X/360 * Pi* R^2 Volume - CORRECT ANSWER Area - CORRECT ANSWER Perimeter - CORRECT ANSWER Cross Multiply - CORRECT ANSWER Volume Of A Cone - CORRECT ANSWER Hyperbola - CORRECT ANSWER A symmetrical open curve formed by the intersection of a circular cone with a plane at a smaller angle with its axis than the side of the cone. Mean - CORRECT ANSWER The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate: Just add up all the numbers, then divide by how many numbers there are. Median - CORRECT ANSWER To find the Median, place the numbers you are given in value order and find the middle number. (If there are two middle numbers, you average them.) Mode - CORRECT ANSWER The number which appears most often in a set of numbers. Range - CORRECT ANSWER The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set. Matrix Multiplication - CORRECT ANSWER Step 1: Make sure that the the number of columns in the 1st one equals the number of rows in the 2nd one. ... Step 2: Multiply the elements of each row of the first matrix by the elements of each column in the second matrix. Step 3: Add the products. Formula for a Sector - CORRECT ANSWER Sectors, Areas, and Arcs. The area A of a circle with radius r is given by A = πr2. The circumference C of that same circle is given by C = 2πr. But these are the formulas for the entire circle. Geometric Formula - CORRECT ANSWER In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Arithmetic Sequence - CORRECT ANSWER An arithmetic progression, or AP, is a sequence where each new term after the first is obtained. by adding a constant d, called the common difference, to the preceding term. If the first term. of the sequence is a then the arithmetic progression is. Colinear - CORRECT ANSWER Lying in the same straight line. Coordinate Plane - CORRECT ANSWER Ray - CORRECT ANSWER A ray is a line with an endpoint that extends infinitely in one direction. Angle Side Angle - CORRECT ANSWER Definition of Angle Side Angle Congruency. ASA congruence postulate states that if two angles and the included side of one triangle are congruent to the two angles and the included side of another triangle, then the two triangles are congruent. Angle Angle Side - CORRECT ANSWER if two angles and the non-included side are congruent to another Side Side Side - CORRECT ANSWER If 3 sides of a triangle are congruent to CSC - CORRECT ANSWER tangent(q) = opp/adj. cotangent(q) = adj/opp. Furthermore, the functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot). Do not be overwhelmed. By far, the two most important trig functions to remember are sine and cosine. Supplementary Angles - CORRECT ANSWER Two angles whose sum is 180 degrees Complementary Angles - CORRECT ANSWER Two angles whose sum is 90 degrees Equidistant - CORRECT ANSWER At the same distance CPCTC - CORRECT ANSWER Corresponding parts of congruent triangles are congruent. Angle Addition Postulate - CORRECT ANSWER If a point lies on the interior of an angle, that angle is the sum of two smaller angles with legs that go through the given point. Corresponding Angle Postulate - CORRECT ANSWER If a traversal intersects two parallel lines, the pairs of corresponding angles are congruent. Parallel Postulate - CORRECT ANSWER Given a line and a point not on that line, there exists a unique line through the point parallel to the given line. Alternate Exterior Angles Theorem - CORRECT ANSWER If a transversal intersects two parallel lines, then the alternate exterior angles are congruent. Corresponding Angles - CORRECT ANSWER Angles that have the same position on two different parallel lines cut by a transversal. Rational Numbers - CORRECT ANSWER Any number that can be expressed as a fraction Integers - CORRECT ANSWER whole numbers and their opposites Irrational Numbers - CORRECT ANSWER Decimal never terminates Real Numbers - CORRECT ANSWER the set of all rational and irrational numbers Natural Numbers - CORRECT ANSWER counting numbers Slope Formula - CORRECT ANSWER Rise Over Run Cotangent - CORRECT ANSWER (in a right-angled triangle) the ratio of the side (other than the hypotenuse) adjacent to a particular acute angle to the side opposite the angle. 30 60 90 Right Triangle - CORRECT ANSWER Sides: 1 : 2 : √3 45 45 90 Isosceles Triangle - CORRECT ANSWER Sides x, x, x√2
